Since graduating college I've become more and more obsessed with studying mathematics. I started going through a text book on differential geometry on my own time. I want to go back to school for a math PhD but I might not be able to so I'm going to learn on my own.
The Christmas list I'm about to give to my mom contains books on most of the remaining material between what I studied in college and what I would need to know for a PhD in math. I want to go through all of them.
In School I took:
Advanced Calc (some schools call it "real analysis")
Intro to probability theory
The books I ordered include one on real and complex analysis, one on abstract algebra, one on linear algebra (I want to review from a different perspective), one on functional analysis and finally one on number theory, the most beautiful field of mathematics.
